Application filed March 20,1917. Serial No. 156,119.

To all LU/tom t may concern.'

Be it known that I, ELMER C. EAGLnsoN, a citizen of the United States,residing at Dayton, in the county of Columbia and State of lllashington,have invented certain new and useful Improvements in Miter-Boxes, ofwhich the following is a specification.

This invention relates to an improved miter box and has as its primaryobject to provide a device of this character adjustable for making mitercuts at various horizontal angles.

The invention has as a further object to provide a miter box adjustablefor making mitcr cuts at various vertical angles.

A still further object of the invention is to provide a device of theabove described character wherein the miter cuts may be made at varioushorizontal and vertical angles simultaneously to thus impart a bevel tothe miters.

A further object of the invention is to provide an arrangement'whereinthe posts of the saw guide may be adjusted upon 'the supporting membertherefor for tilting the posts with respect to the vertical and thusinclining the saw for making miter cuts at various vertical angles andto further provide an improved mounting for the said posts. l

And the invention has as a still further object to provide anarrangement wherein the posts of the saw guide will be frictionally heldat adjustment and wherein means will also be provided for rigidlylocking the post at adjustment.

Gther and incidental objects will appear as the description proceeds andin the drawings wherein 1 have illustrated the preferred embodiment ofthe invention and wherein similar reference characters designatecorresponding parts throughout the several views:

Fig. 11 is detail showing the catch.

In carrying out the invention, my iirproved miter box is formed with abase 10 supported by suitable legs 11. Formed on the forward side of thebase substantially midway of the ends thereof, is a segmental plate 12provided, upon its outer edge, as particularly shown in Fig. 1, with asuitable scale having graduations indicating the degrees of a circle.Upon its inner side, the plate 12 is undercut to provide a flange 1B andformed in the lower edge of the plate is an arcuate series of notchesone of which is shown at 14. Opposite the plate 12, the base 10 isformed with a bearing 15 and pivotally mounted upon this bearing toextend horizontally beneath the base is an arm 16 of a saw guide, thesaid arm projecting at opposite sides of the base. This arm, at its rearextremity, is formed with a socket 17 and at its forward extremity, isprovided with spaced sockets 18 and 19 respectively.

Vpurpose of these sockets will presently ap- 'Y cate upon the arm 16 andis operable by '19 respectively.

cams 22 arranged at opposite sides of the saidlarm and engaged by a yoke23 pivoted, at its inner extremity, upon the arm immediately in the rearof the pin 21. rl`he arms of the yoke 23 are received by guide pins 24and interposed between the said yoke arms and the arm 16 to surround thesaid guide pins are springs 25 normally urging the free extremity of theyoke .downwardly and acting upon the cams 22 toyieldably force the catchpin 21 upwardly for engagement within one of the notches 14.Accordingly, by

properly manipulating the yoke 23, the arm 16 of the saw guide may beadjusted to various horizontal angles which may be read upon the scaleat the front edge of the plate 12. Mounted upon the base 10 to extendlongitudinally thereof, isthe bed 26 of a box proper and associated withthis bed to extend at substantially right angles thereto is the fence 27of the box. Extending rearwardly from. the'base in a plane substantiallyparallel with the bed 26 are bracketsy 28 and adjustably Y connectedwith these brackets by suitable set screws as particu-l larly shown inFig. 2, are work clamps. 29 shiftable transversely of the bed. l All ofthis structure,'as thus described, with the exception of theV fence 27may be of any suitable design, it onlyv being necessary for the purposesof the present invention that the arm 16 of the saw guide be pivoted foradjustment'in a horizontal plane with respect to the bed 26 of the boxproper and provided with sockets similar to the sockets 17, 18 and Thefence 27 of the box proper is, as par ticularly shown in Fig. 2,provided int-ermediate its ends with a substantially V- shaped notch 30andy fitting in the said notch are swingingly mounted fence sections 31confronting, at their inner ends, to Ydefine a slot 32 adapted Vtoreceive the saw when making ordinary miter cuts at various horizontalangles. Connected with the fence sections 31 are supporting arms 33therefor which, at their outer extremities, are mounted upon pivot bolts34 fitted through A the fence and provided with suitable wing nuts toclamp against the arms. The fence sections may thus be adjusted to theposition shown in Fig. 2 to be held at adjustment by the said bolts ormay be swung to the position shown in Fig. 1, projecting beyond oppositeends of the fence with the bolts 34 operable for holding the said fencesections at adjustment. ln this latter position of the ,fenceY sections,unobstructed movement of the saw with respect to the verticalwithin thenotch 30 will be permitted.V Con-V the fence sections 31 are spacedfingers36 arranged to confront the innerside face of the fence. Thesefingers are thus adapted to hold the fence sections 31 against lateraldisplacement within the notch 30.

Mounted upon the arm 16 of the saw guide are spaced socket members forthe f posts of the saw guide. These socket members each include a body37 provided with spaced upstanding side walls 38 and 39 respectivelywith the body cut away between thesaid walls to define an arcuate socket40. Depending from the body is a cylindrical shank 41 andas willnow beobserved upon reference to Fig. 4, the socket member is split mediallyto define coacting mating sections 42 and 43 respectively, the wall 38being carried by the section 42 while the wall 39 is carried by thesection 43. Also,'each of the sections carry a portion ofthe shank 41.Formed in the bottom of the socket 40 upon the section 42A of the socketmember is, as shown in detail in Fig. 6, an arcuate shoulder 44projecting inwardly from the wall 38 of the said section. At one end,this shoulder is formed with a suitable notch while, at the opposite endof the shoulder, the wall 38 is soV formed lwith an enlargementproviding a Y upon the said shoulder is an arcuate resilientA frictionband 47 provided, at one extremity, with a hook 48 engaged within saidnotch and at its opposite extremity with a threaded shank orY terminal49 extending loosely through the opening 46 and fitted with a nut 50engaged with the seat 45. s will be clear, the nut 50 may beadjusted-upon the Ishank 49 for shortening the radius of the band.Formedin the upper margin of the wall 38 is an arcuate notch 51 andprojecting laterally from the said wall and arranged concentric to thenotch 51 as well as concentric to the shoulder 44 and band 47 is anarcuate bearing shoulder 52. Projecting laterally from the shoulder 44,at its extremities, are lugs 53. Y j

The section 43 of the socket member is, as shown in detail in Fig. 7,formed with an iio arcuate Ybearing shoulder 54V projecting latfrom theshoulder, at its extremities, vare lugs 56. Formed in the upper marginof the wall 33 is an arcuate notch 57 similar t0 the .notch 51 of thesection 42 and of equal radius therewith. As will now be observed uponreference to Figs. 3 and 4 of the drawings, the sections 42 and 43 ofthe socket members respectively are arranged to seat flat against eachother with the lugs 53 and 56 of the said members abutt-ing forsupporting the walls 38 and 39 of the said socket members in spacedrelation. The Shanks 41 of the said socket members are arranged toremovably fit within the sockets 17, 18 and 19 of the arm 16 of the sawguide and for ordinary purposes, one of the said socket members is, asbest shown in Fig. 3, fitted within the socket 17 while the other of thesaid members is tted within the socket 1S. Threaded into the shanks 41of the said socket members are expander bolts 5S Vdetach-ably connectingthe said socket members with the arm of the saw guide.

Arranged to coperate with the socket members are substantiallycylindrical hubs 59 for the posts of the saw guide. The hubs 59 are eachformed with a radial saw receiving slot 60 intersecting the axis of thehub and at opposite sides of which are mounted upstanding parallel rods61 forming one of the posts of the saw guide, these rods being screwthreaded into the hub or secured thereto in any'other suitable manner.Upon one side, the hub is cut away to provide a substantially circularchannel 62 concentric to the axis of the hub and of equal radius withthe bearing shoulders 52 respectively ofthe socket members. Projectinglaterally from the hub, at the inner end of the slot 60, is an arcuatebearing shoulder 63 also concentric with the axis of the hub.

The hubs 59 are rotatably received-betweenV the walls 38 and 39 of thesockets 40 to rest upon the shoulders 54 of the sections 43 of thesocket members with the shoulders 52 of the sections 42 of the saidmembers fitting within the channels 62 of the ,hubs so that the bearingflanges 63 thus seat within the said shoulders. The hubs 59 may thus berocked upon the socket members with the friction bands 47 confrontingthe outer faces of the said hubs.v Formed in the outer faces of the hubs59 are a plurality of sockets 64 corresponding to the gra'duations ofscales 65 upon the sections 43 of the socket members and arranged tocoperate with the said scales are pointers 66 carried by the hubs.

As illustrated in Figs. 1 and 3 of the drawings, the posts of the sawguide are supported by the hubs 59 in substantially parallel relationand slidably vmounted upon the rods 61 of the said posts are sleeves 67which may be of any suitable character and are adapted to receive a saw,as conventionally illustrated at 68. Connected with the sleeves 67 arespring pressed catches 69 for automatically locking the sleeves tosupport the saw in elevated position upon the posts of the saw guide.These catches 69 may also, be of any conventional design.

Mounted upon the upper extremities of the posts of the saw guide, is aconnecting bar 70 therefor, shown in detail in Fig. 9 of the drawings.This bar is'provided with a plurality of enlargements 71, 72 and 73respectively, spaced apart to correspond to the spacing of the sockets17, 18 and 19. Formed in each of the said enlargements are spacedopenings 74. The upper ends of the rods 61 of each of the posts of thesaw guide are, as shown in detail in Fig. 10, cut away to provide spacedlugs 75 adapted to engage within the openings 74 of the saidenlargements respectively and in mounting the bar in position, the saidbar is preferably arranged with the enlargement 71 at the front post ofthe saw guide so that the enlargement 72 will be disposed at the rearpost of the said guide. Connecting the bar 70 with the said posts areclamps each including a yoke 76 extending between the rods of one of thesaw guide posts and removably fitted through the yoke to extend throughthe bar are screws 77 threaded into the rods. Mounted upon the yoke is aclamp screw 78 adjustable to engage the bar between the post rods. Theclamp screws 78 may, therefore, be operated to tightly bind the bar 70in engagement with the lugs 75 of the rods of the saw guide posts withthe bar thus supporting the rods of each post against movement relativeto each other as well as rigidly supporting the posts spaced apart.

As will now be seen, the arm 16 may be swung upon the base 10 to adjustthe saw for making miter cuts at various horizontal angles. For making amiter cut at a vertical angle, the sections 31 of the fence 37 of thebox proper are first displaced when the saw is tilted by rocking thehubs 59 of the posts of the saw guide within the socket members thereforto accordingly incline the said posts. Upon consulting either of thescales 65 upon the socket members, the vertical angle of adjustment ofthe saw guide posts may be easily determined by means of the pointers 66when, by manipulating the set screws 55 to engage within correspondingones of the sockets 64, the posts of the saw guide may be rigidly lockedat adjustment. However, it may not always be desirabie to thus rigidlylock thel posts of theV saw guide and the. friction bands 47 areaccordingly provided. By adjusting the nuts 50 of the said bands, thesebands may 'be tensioned against the hubs 59 of the saw guide posts tofrictionally engage therewith and accordingly tension the hubs in theirrocking movement within the socket members. The frictional action ofthese bands upon the hubs 59 will, therefore, under ordinary conditions,suffice to hold the posts of the saw guide at adjustment when y swungintoV angular relation with respect I saw guide may be adjusted to tiltthe saw for making miter cuts at various vertical angles and in thisconnection, it is to be Vobserved that the slots 60- in the hubs 59 ofthe saw Lguide posts are arranged to register with the notches 51 and-57 of the sockets for the hubs so that the saw may, as illustrated inFig. l, be received within the said slots and notches to rest againstthe bed 26 of the box proper. Furthermore, particular attention isdirected to the fact that owing to the mounting of the hubs 59 and thearrangement of the saw between the rods 6l of the posts of the sawguide, the saw will always be supported to extend radially I of the axesof the hubs and will thus be held to accurately cut a miter at theparticular angle of adjustment of the said posts.

In view of the preceding description, it will now be understood that thearm 16 of the saw guide may first be adjusted to any desired horizontalangle and the posts of the saw guide then adjusted to any desired anglewith respect to the Vertical so that the saw may then be operated formaking a miter cut at the said horizontal and vertical anglessimultaneously to thus impart a bevel to the miter.

It will therefore be seen that I provide a guide may be engaged withinthe socket 19 of the arm 16 when the enlarged portion 73 of theconnecting bar 70 will then be disposed to receive the rods of the rearpost of the saw guide. This arrangement may sometimes be found necessaryin cutting wide timbers and it is to be observed that the rod 7 0 will,at all times, rigidly support the posts of the saw guide forsimultaneous ad`ustment;
